302 TEANSACTIONS OF THE [1895 



were taken (a ring of snow was round each nest, and it was two 

 feet deep on the ground) ; while on May 6 ('94, Wholey) a set 

 nearly incubated was collected, and on May 31 ('91) a second 

 set was taken. Sets are 5 of 2 ; 4 of 3, and 4 of 4. 



Outside the breeding season, this species, like borealis may 

 sometimes be seen in flocks, more often in bunches of 3 or 4 to 

 10, but generally singly or in pairs. 



Buteo latissimus (343). Broad-winged Hawk. 



Resident, but not common. On April 27 ('91) a set of 

 three eggs was taken; on May 19 ('92, Blogg) a set of two, 

 and on May 23 ('92, J. H. Fisher, Jr.) a set of three nearly 

 incubated. At Sandy Springs, a set of three was taken April 

 9 ('91); one of three in May ('92); one of two on May 15 

 ('92), and another of two on May 22 ('92, Stabler). 



The three Buteos are the hawks usually shot by our farmers, 

 because they are large, fly slow, and are called "hen-hawks," 

 while the much smaller, swift flying, Falcos and Aecipiters, 

 that may at times take chickens, escape. 



Archibuteo lagopus sancti-johannis (347a). American 



Rough-legged Hawk. 



"Along the Delaware, below Philadelphia, it is still found in 

 considerable numbers from November to the end of March" 

 (Birds E. Pa. and N. J., 87). It does not appear to be 

 numerous in Maryland. On January 24, '92, in Dulaney's 

 Valley, one sitting on a tree allowed me to drive slowly past 

 within twenty feet of it. Dr. M. G. Ellzey says this species 

 was very numerous in Howard County during the winter and 

 spring of '87-88 (Forest and Stream, xxxii, 212). At Sandy 

 Springs one was shot by Mr. Leizear on March 17, '88 

 (Stabler). One was seen on the Virginia side of the Potomac, 

 opposite Washington, on December 29, '79, by Mr. H. W. 

 Henshaw (A. C, 88-9), and it has been taken in the District 

 of Columbia (L. M. McCormick, Auk, i, 397).
